PROBLEM TO BE SOLVED: To provide an improved ultrasonic surgical shears and an ultrasonic surgical shears tissue pad. SOLUTION: The ultrasonic surgical shears tissue pad has a tissue-pad body including a base material and at least one filler material. An alternate ultrasonic surgical shears tissue pad has a tissue-pad body having adjoining first and second regions, wherein the first region includes a first material and the second region includes a second material. The ultrasonic surgical shears includes an ultrasonic surgical blade and a clamping arm which is operable to open and close toward the blade and which has a transversely and resiliently flexible distal tip. An alternate ultrasonic surgical shears includes an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, and a tissue pad attached to the clamping arm and having a clamping surface, wherein at least a portion of the tissue pad is resiliently flexible in a direction substantially perpendicular to the clamping surface.
